DIAGNOSTIC TROUBLE CODE (DTC) – P0335 MAGNETIC CRANKSHAFT
POSITION SENSOR ELECTRICAL ERROR
Circuit Description
The 58X reference signal is produced by the crankshaft
position (CKP) sensor. During one crankshaft revolu-
tion, 58 crankshaft pulses will be produced. The engine
control module(ECM) uses the 58X reference signal to
calculate engine rpm and CKP. The ECM constantly
monitors the number of pulses on the 58X reference cir-
cuit and compares them to the number of camshaft posi-
tion (CKP) signal pulses being received. If the ECM
receive and incorrect number of pulses on the 58X refer-
ence circuit, DTC P0335 will set.
Conditions for Setting the DTC

This DTC can be stored in “key-on” status.

Extra or missing pulses is detected between consec-
utive 58X reference pulses.

The value of Magnetic Crankshaft position sensor is
higher than 0.2V.

The minimum value of Magnetic Crankshaft position
sensor is less than 1.5V.

The Maximum value of Magnetic Crankshaft position
sensor is higher than 2.2V.
Action Taken When the DTC Sets

The Malfunction Indicator Lamp (MIL) will illuminate.

The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.
A history DTC is stored.
Conditions for Clearing the MIL/DTC

The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault.

A history DTC will clear after 40 consecutive warm-up
cycles without a fault.

DTC(s) can be cleared by using the scan tool.
DIAGNOSTIC AIDS
An intermittent may be caused by a poor connection,
rubbed-through wire insulation or a wire broken inside
the insulation. Check for :
Poor connection – inspect the ECM harness and con-
nectors for improper mating, broken locks, improperly
formed or damaged terminals, and poor terminal-to-wire
connection.
Damaged harness – inspect the wiring harness for dam-
age. If the harness appears to be OK, disconnect the
ECM, turn the ignition ON and observe a voltmeter con-
nected to the 58X reference circuit at the ECM harness
connector while moving the connectors and the wiring
harness related to the ECM. A change in voltage will in-
dicate the location of the fault.
Review the failure records vehicle mileage since the
diagnostic test failed may help determine how often the
condition that caused the DTC to be set occurs. This
may assist in diagnosing the condition.

DIAGNOSTIC TROUBLE CODE (DTC) – P0351 IGNITION SIGNAL COIL A FAULT
Circuit Description
The engine control module (ECM) provides a ground for
the electronic spark timing 1 circuit. When the ECM re-
moves the ground path of the ignition primary coil, the
magnetic field produced by the coil collapses. The col-
lapsing magnetic field produces a voltage in the secon-
dary coil which fires the spark plug. The circuit between
the ECM and the electronic ignition system is monitored
for an open circuit, short to voltage, and low voltage.
When the ECM detects a problem in the spark timing 1
circuit, it will set DTC P0351.
Conditions for Setting the DTC

This DTC can be stored in “key-on” status.

Time of fault fall occurrence is greater than time of the
DIS fall occurrence.
Must receive more than 40 failure within 80 test
cycles.
Action Taken When the DTC Sets

The Malfunction Indicator Lamp (MIL) will illuminate.

The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.

A history DTC is stored.
Conditions for Clearing the MIL/DTC
